Federal prosecutors have issued subpoenas to the sons of former New Orleans Mayor Ray Nagin in an effort to compel them to testify and to present documents that could serve as evidence against their father, the WDSU I-Team has learned.

The bill of information -- which is similar to an indictment -- accuses Rodney WIlliams of bribing "Public Official A" in exchange for lucrative city contracts. The official is not named, but the dates of the alleged bribes coincide with Nagin's term of office and the bill of information specifies that "Public Official A" was an agent of the city from 2002-2010, when Nagin served as mayor.

Williams is accused of paying off the official "for his assistance in connection with a series of transactions," and of devising a "scheme and artifice to defraud the City of New Orleans."

Williams was, at the time, an executive with Three Fold Consultants, which received no-bid contracts during Nagin's tenure as mayor.

A bill of information indicates the defendant is cooperating with prosecutors.

Nagin's attorney, Robert Jenkins, told WDSU he was unaware of the development and had no additional comment.

Nagin has not been charged with any crime, but several business associates have been accused of criminal misconduct since Nagin left office.

The charges against Williams had been under seal since they were filed on Nov. 16. Williams was president of Three Fold Consultants at the time of the alleged bribes but is no longer with the company.
